In the wake of the establishment of the State of Israel in 1948, it has often been alleged that King Abdullah I of Jordan and the Zionist movements colluded to partition Mandate Palestine between them, while Great Britain, the retreating imperial power, gave them tacit approval to do so. Here, Tancred Bradshaw challenges these allegations, looking at the complex and often strained relations between the emerging states of Jordan, Israel, and the at first hegemonic, and then crumbling, British Empire. Using a wide range of primary sources which have previously been largely ignored, Britain and Jordan offers an essential re-examination of the relationships which were to shape the Middle East as it is today. It thus contains vital analysis for anyone involved in the study of the Middle East, its politics and history, as well as the demise of Britain's empire in the region.
